Outside My Demographic
Small Jones went back to the Commons where he used to kick it back last year. The new crowd there was crazy young and none of his regular peeps were there. All they had at the bar was a spritzer menu. He told me it was a very "omd" moment and he had to bolt.

OMD: Oh my dinkles.

-A term commonly used by band geeks during marching season and even during concert band season. Instead of saying "Oh, my dinkles," a band geek may just exclaim "omd." Dinkles are a special type of shoe that marching band uses on the field.

-Also, OMD may be used instead of OMG. Just because it's a band geek thing.

-First used: when a band geek was drawing band stuff on her folder in her english class, her fellow band geek asked her,
"Cool treble clef! Didn't you say you were going to draw your dinkles?"
She then said, "OMD! You're right!" and drew the dinkles.
1: So, are you forgetting anything?
2: No. Oh wait, OMD!

1: Hey, did you know that he didn't make All County Jazz Band?
2: OMD! NO WAY!
